VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 457,435, dated August 11, 1891.

Application filed October 31,

T 60% whom it may concern:

Be it known that I-, ARTHUR L. GARFORD, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Velocipedes, of which the following is such a full, clear, and exact description as will enableot-hers skilled in the of a Safety bicycle having my improved mechanism, and Fig. 2 is a horizontal section on line 2 2 of Fig. 1.

Referring to the parts by letters, A represents the frame of a Safety bicycle, B the rear (and driving) wheel, and B the front wheel thereof.

0 represents the crank-shaft, which is suitably journaled in bearings c 0, supported and braced by the arms a a a of the frame. Keyed or rigidly secured in some other ap propriate manner to the axle of the rear wheel B is a bevel-gear b, and similarly secured to the crank-shaftis an othe r bevel-gear c.

D represents a shaft, which is mounted in suitable bearings in the frame and has secured to its ends the bevel-gears (Z cl, of which the former meshes with the bevel-gear c and the latter with the bevel-gear b, abov described.

The hub of the driving-wheel B is cupped, as shown, and the bevel-gear 1) lies almost wholly within the recess thus formed. The bevel-gear c is secured to the crank-shaft out-- side of the brace a, and its-teeth are on its inner side. The end of the shaft D nearest the crank-shaft has its bearings in a piece 0 which is cast or forged integral with the.

1890. Serial No. 369,927. (No model.)

crank-shaft bearing a. The end of the shaft D nearest the rear wheel is journaled in a piece formed as an integral part of the piece in which is the bearing of the driving-axle. The part a of the frame may be brazed or otherwise secured to this piece a. The brace a is a tube which surrounds the shaft D, and its ends screw into the bearing-pieces c and a The shaft D is thus protected from danger of being bent or broken, and its bearings are to a great extent protected from dust.

The bearing-piece C is provided with a transverse vertical slot 0 in which lies most ,of the beveled geard, and the bearing piece a is similarly provided with a transverse vertical slot a in which lies most of the beveled gear 01. By thus slotting the bearingpieces 0 and A a working space for the beveled gears is provided. Most of the gear is protected from injury, and means are provicled to which any suitable covering for said bevel-gears hear such relation to each other that the rear wheel makes three revolutions while the crank-axlemakes two.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a velocipede, in combination, the driving-axle, a wheel having a cupped hub secured thereto, a bevel-gear secured to said axle and lying in the recess in said hub, the crank-axle and a bevel-gear secured thereto,

-a shaft, bevel-gears secured on each end thereof, and bearings for said shaft secured to the velocipede-frame, substantially as and. for the purpose specified.

- 2. In avelocipede,iu combination, the driving-axle and a bevel-gear secured thereto, thecrank-axle and a bevel-gear secured thereto, two pieces rigidly secured to the velocipedeframe, one near the crank-shaft and one near the driving-shaft, eachof said bearing-pieces havingv transverse vertical slots, a shaft mounted in said bearing-pieces, and two bevel-gears secured to the ends of said shaft and extending through said slots and meshing with the bevel-gears on the crank-shaft and driving-axle, respectively, substantially as and for the purpose specified.

ARTHUR L. GARFORD.
